We know nuts are the healthiest source of fat, cutting our risk of dying from a heart attack in half. but what about avocados: friend or foe? Is guacamole bad for you? neither good nor bad? Or, pass the guacamole?
The chips you may eat them with are bad, but avocados are good for you. Helps prevents cancer, may help with arthritis, boost our immune system, and lower our cholesterol. We used to think oranges were the best fruit source of cholesterol-lowering phytosterols. That is, until avocados were tested.

Doctor's Note

For the entire saga, see the two subsequent videos Are Avocados Good for You? and Are Avocados Bad for You? as well as the follow-up Any update on the scary in vitro avocado data?

  • Veguyan

    Now in Volume 5 of your Latest in Clinical Nutrition, you put the jury out on avos saying they may destroy healthy cells along with cancer cells because they seem to do so in a petri dish.

    God help us! What can we vegans enjoy if not an avocado? Do I have to have cancer to enjoy an avocado?

    • Michael Greger M.D.

      Oh, I know! That was definitely one of the shockers of the year. I’ll post those two avocado videos from the new DVD here on the site. Basically there’s a natural insecticide compound called persin produced by the avocado tree that gets into the fruit that a new study suggests may cause chromosomal damage. But this was in vitro, meaning outside the body (like in a test tube or petri dish). Even people who love guacamole don’t shoot it up like heroin, so before that avocado compound makes its way to our body tissues it must survive stomach acid, digestive enzymes, and the detoxifying might of our liver. So the jury is indeed still out, so I recommend moderating our intake of avocados until we know more. Sorry–don’t shoot the messenger!

    There’s still lots of healthy vegan food you can enjoy. I have avocados once in a while as guacamole, but it’s definitely not a staple of my diet.

    I run if you’re looking for oil free, low fat whole food recipes.
